Simulated and Cleaned Dataset for Data Processing Tasks

This dataset was created as part of a data management and processing project. It contains simulated and cleaned data used to demonstrate data preprocessing techniques such as duplicate removal, handling missing values, and format standardization. The dataset includes structured tabular data with variables such as age, gender, and measurement values. Dates are formatted in ISO standard (YYYY-MM-DD), and numeric values are normalized between 0 and 100. This dataset can be used for educational purposes, data cleaning practice, and testing data analysis workflows.
